add

ob_start();

to the top o fall your php pages.

doesnt seems to work

headers are kinda gay, well some what.

This should be the last thing called to the page, this line would normally follow a exit() function which stops the script.

The absolutly critcial thing to remember about the header() function is that it must be called before anything is sent to the web browser. This includes HTML or even blank spaces.. No echo()s or print() statements, blank lines outside of PHP tags and even include files that do the same.

I dont like this:

// Set some header info
$headers = "To: Your Name \r\n";
$headers .= "From: $name <$email>\r\n"; // Don't change
$headers .= "Reply-To: $email\r\n"; // Don't change

header("Location: sendmail.php");

Why do you want to send it back where you are? Try using a full absolute path ie http://www.url.com/page.php And whats on line 38?

when the mail is send i want to go back to the homepage but how?
adn this is on line 38

37:header("Location: sendmail.php"); 
38:// After the mail has been sent, redirect the visitor to a new page  

[edit]oke problem is done how do i send i back to the home page?[edit]
